Patented Oct. 29, 1935 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to bottle caps or closures and more specifically to improvements in bottle caps such as disclosed in Patent No. 1,612,- 927 granted to me on January 4, 1927. In said patent is disclosed a bottle cap embodying means whereby a portion of the cap may be swung-so as to sever a portion of the sealing disc and provide an opening in the cap thru which the contents of the bottle may be poured.

The primary object of the present invention is to provide a bottle cap or closure of this character embodying an arrangement to assure severing of a substantial portion of the sealing disc so that the contents of the bottle may be poured freely.

A further object of the present invention is to provide an improved bottle sealing cap of this character permitting removal of the contents of the bottle without the necessity of employing some form of instrument to wholly remove the cap from the bottle, and which cap will also allow for subsequent closing of the bottle after partiallyremoving the contents thereof.

Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken inconnection with the accompanying drawings, forming a part of thisspecification and in which drawings:--

Figure 1 is a top plan view of the cap constructed in accordance with the present invention.

Figure 2 is a view looking at the inner side of the cap.

Figure 14 is a perspective view of the inner member or plate section for the opener shown in Figure 13. 5

Referring first to the form of bottle cap or closure shown in Figures 1 to 7 inclusive, the same comprises a metallic cap I0 having the form of the well known crown cap and embodying a discshaped top portion provided about its edge 10 with the usual scalloped flange |2 adapted to be crimped about the end of the neck of the bottle A to form a closure therefor. Provided on the cap I0 is an opener member l4 capable of being swung with respect to the cap for severing a sub- 15 stantial portion of the sealingdisc I5 whereby an opening is formed thru the bottle closure so that the contents of the bottle may be poured out.

Formed in the top portion 01' the cap |0 is an elongated, preferably rectangular-shaped opening l6 provided along each of its longer side edges with an inwardly extending blade or cutter These parallel blades IT as will be observed in Figure 4, are formed as a part of the top portion II and have a depth less than the thickness of the sealing disc l5 so that there is an uncut portion of the disc beneath the edges of the blades. Formed integral with the top portion H and bent inwardly therefrom at one end of the opening i6 is a tongue or arm 3 adapted to extend with a sealed fit thru the sealing disc l5. As shown more clearly in Figure 6, this tongue is of a width less than the width of the opening Hi to provide material for formation of the blades l1 thruout the length'of the opening I6.

Referring now to the opener member M, the same is preferably formed of suitably thin metal and of one piece construction providing an attaching portion 20 which is secured at one end as by soldering, welding or the like to the outer side of the top portion II at that end of the opening I6 from which the tongue I8 is inwardly bent. Struck inwardly from this attaching portion 20 is an inner plate portion 2| connected at one end to the free end of the portion 20 by an arm 22 which extends with a sealed fit thru the sealing with a hook 23 which preferably has a hinge connection with the inner end of the tongue I 8 whereby the free end of the plate is held against the sealing disc. Connected at one end to the free end of the attaching portion and extending rearwardly in overlying relation thereto, is a combined cover and lift plate 24 and. this plate 24 aside from forming a cover over the opening I6, provides .a lift which may be raised by ones fingers for opening the bottle. Striking out of the inner plate 2| provides a pair of spaced apart connecting arms 25 which serve to assist in holding the, free end of the attaching portion 20in position against the cap "I.

In use of the cap, ones finger is first placed at the free end of the lift plate 24 and the plate I raised sufficiently to permit the same to be gripped between the fingers. Now, by pulling upon the lift 24 the inner plate 2| will swing upwardly about the hook 23 as shown in Figure .5 thus severing a substantial portion of the sealing disc and pulling the severed portion of the disc outwardly thru the opening l6. As the plate 2i movement of the opener. I

Referring now to the form of invention as disclosed in Figures 8 to 14 inclusive, the form of bottle cap or closure shown therein comprises a metallic cap 26 embodying a disc-shaped top portion 21 provided about its edge with the sealloped flange 28 to be crimped about the end of the bottle A. Formed in the top portion 21 of the cap 26 is an elongated, preferably rectangularshaped opening 29 provided along each of its longer side edges with an inwardly extending blade or cutter 30 formed integral with the top portion and having a depth less than the thickness of the sealing disc 3|.

The opener member designated as a whole by the numeral 32 is formed of suitably thin sheet metal and embodies an outer or major portion 33 shown in detail in Figure 13 and an inner plate portion 34 shown in Figure 14. The, outer or major opener portion 23 is of one-piece construction providing an attaching portion 35 and a combined cover and lift plate 36 bent to extend in overlying relation to the attaching portion 35. The outer opener portion 33 is of substantially rectangular-shape and of a size slightly larger than the opening 29 in the cap 26 as shown in Figures 10 and 11. The attaching portion 35 is secured at its free end as by .soldering, welding, or the like to the outer side of the top portion 21 beyond one end of the opening 29. Struck'inwardly from the attaching portion 35 adjacent each end thereof are tongues or arms 38 which are adapted to extend with a sealed fit thru the sealing disc 21 adjacent opposite ends of the opening 29. 6

The inner plate portion 34 which is adapted to engage upon the inner side of the sealing disc 21 is of rectangular shape and of a size substantially equal to the size of the opening 29, with the width of the plate being slightly less than the spacing between the blades 30 to permit the plate to be pulled thru the opening. The inner plate portion 34 is provided adjacent each end wit a slot 40 for receiving the ends'of the arms 38 which extend thru the slots and preferably have their ends bent over upon the inner plate as clearly shown in Figure 10. In "order to prevent the bent ends of the arms 38 from possibly straightening out and pulling thru the sealing disc, the arms may be secured as by soldering or the like as at 42. This soldering 42 will not be absolutely required if the opener portion 33 is 5 formed of heavy gauge metal altho it is preferred that the opener be formed of metal sufficiently thin to permit ready raising of the lift plate 36 by ones finger and without requiring use of any instrument. The inner plate 34 will insure severing 10 of a substantial portion of the sealing disc 21 so that a suitably large hole is formed thru the closure cap.

Thus, in both forms of the invention there is a metallic plate arranged inwardly of the sealing l5 disc and connected thru the sealing disc with an outer opener portion providing means whereby a pull may be exerted upon the innenplate to pull the inner plate thru an opening in the metallic cap and thus sever a portion, of the sealing disc.

Changes in detail may be made to the forms of invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.
